Extant marine mammals represent multiple recolonizations of the marine environment by terrestrial mammals. Freed from the constraints of terrestrial locomotion, cetaceans (whales, dolphins, and porpoises) and pinnipeds (seals, sea lions, and walruses) diversified and spread throughout the world’s oceans. For those animals, land masses represented barriers, and their evolutionary history has bee...

The boundary between the crust and the mantle was discovered by Mohorovicic in 1909 under the European continent. Subsquent research in this century established the major differences between the continental and oceanic crust; a typical thickness for the continental crust is 30-50 km while a typical thickness for me oceanic crusts is 6 km. In terms of history the continental crust contains a muc...

The structural and subsidence history of the Neogene Transylvanian basin is reviewed in order to analyse its relation to the tectonic and erosional history of the surrounding Carpathian mountains that has been defined by apatite fission track data from previous studies. The main processes studied are redistribution of mass by erosion, and tectonic loading. A mass balance is calculated between m...

In a previous paper, we derived plate tectonic models for continental accretion from the early Archaean (3800 m.y.B.P.) until the present. The models are dependent upon the number of continental masses, the seafloor creation rate and the continental surface area. The models can be tested by examining their predictions for three key geological indicators: sea level changes, stable isotopic evolu...

[1] The southern Canadian foreland fold-and-thrust belt (FFTB) (SW Alberta–SE British Columbia) records the interplay between foreland basin evolution with the deformingwedge and thus controls the regionalscale overburden and exhumation history. Overburden estimates are typically based on the assumption that peak burials were reached by sedimentary burial prior to the emplacement of thrust shee...

Sea level changes have occurred throughout Earth history. The magnitudes and timing of sea level changes are extremely variable. They provide considerable insight into the tectonic and climatic history of the Earth, but remain difRcult to determine with accuracy. Sea level, where the world oceans intersect the continents, is hardly Rxed, as anyone who has stood on the shore for 6 hours or more ...

The surface of Venus displays several tectonized terrains in which the morphologic characteristics of the original materials are almost completely erased by superposed tectonic structures whose large dimensions (»100 km) suggest formation related to mantle convection. The characteristics of these tectonized terrains are in contrast to volcanic units in which tectonic structures are less signifi...

Tectonic setting exerts fi rst-order control on basin formation as refl ected in basin subsidence history. While our approach ignores the effects of fl exural loading and eustatic sea-level change, consistency of backstripped subsidence histories (i.e., with local loading effects of sediment removed) suggests consistent tectonic driving mechanisms in each tectonic setting, with the possible exc...
